Factibilidad y efectos de la prehabilitación en cirugía cardiaca. Estudio preliminar / Feasibility and effects of prehabilitation in cardiac surgery. Preliminary study

Objetivo: Evaluación de la factibilidad de un programa de prehabilitación multimodal y su efecto sobre la capacidad funcional en pacientes candidatos a cirugía cardiaca electiva. Métodos: Estudio piloto realizado desde julio de 2017 hasta junio de 2018 en pacientes candidatos a revascularización miocárdica y/o recambio valvular. El programa consistió en: 1) programa de entrenamiento físico supervisado, 2) incentivación respiratoria, 3) soporte nutricional y 4) entrenamiento en mindfulness. Se realizó una evaluación previa al inicio del programa y al finalizar el mismo (preoperatoriamente). Resultados: Todos los pacientes, excepto uno que rechazó la cirugía, completaron el programa, que tuvo una duración media de 45 días. Ningún paciente presentó complicaciones relacionadas con el programa. El programa indujo un aumento significativo de la capacidad funcional medido por el test de la marcha de seis minutos (510,7+62m vs. 534,3+71m; p=0,007) y el test de la silla (13,2+4,7 vs. 16,4+7 repeticiones; p=0,02), así como un aumento del nivel de actividad física medido mediante el cuestionario de actividad física de Yale (37,6+20 vs. 54,2+27; p=00029). Conclusiones: La prehabilitación multimodal en pacientes candidatos a cirugía cardiaca electiva es factible y aumenta la capacidad funcional preoperatoriamente sin asociarse a complicaciones. El presumible impacto beneficioso de esta mejora sobre la incidencia de complicaciones postoperatorias y estancia hospitalaria requiere ser investigado.(AU)

Objective: Evaluation of the feasibility of a multimodal prehabilitation program and its effect on functional capacity in patients candidates for elective cardiac surgery. Methods: Pilot study conducted from July 2017 to June 2018 in patients candidates to myocardial revascularization and/or valve replacement. The program consisted of: 1) supervised exercise training program, 2) breathing incentive exercises, 3) nutritional support, and 4) mindfulness training. An evaluation was carried out prior to the start of the program and at the end of it (preoperatively). Results: All patients except one who refused surgery, completed the program, which lasted an average of 45 days. No patients presented complications related to the program. The program induced a significantly increase in functional capacity measured by the six-minute walking test (510.7+62m vs 534.3+71m, P=.007) and the chair test (13.2+4, 7 vs 16.4+7 repetitions, P=.02), as well as an increase in the level of physical activity measured by the Yale physical activity questionnaire (37.6+20 vs 54.2+27; P=00029). Conclusions: Multimodal prehabilitation in patients candidates for elective cardiac surgery is feasible and it increases functional capacity preoperatively without being associated with complications. The presumed beneficial impact of this improvement on the incidence of postoperative complications and hospital stay, requires further investigation.(AU)

Feasibility and effects of prehabilitation in cardiac surgery. Preliminary study.

Prehabilitation programs that combine exercise training, nutritional support, and emotional reinforcement have demonstrated efficacy as a strategy for preoperative optimization in abdominal surgery. The experience in cardiac surgery, one of those associated with greater morbidity and mortality, is anecdotal. OBJECTIVE: evaluation of the feasibility of a multimodal prehabilitation program and its effect on functional capacity in patients candidates for elective cardiac surgery. METHODS: Pilot study conducted from July 2017 to June 2018 in patients candidates to myocardial revascularization and/or valve replacement. The program consisted of: 1) supervised exercise training program, 2) breathing incentive exercises, 3) nutritional support, and 4) mindfulness training. An evaluation was carried out prior to the start of the program and at the end of it (preoperatively). RESULTS: All patients except one who refused surgery, completed the program, which lasted an average of 45 days. No patients presented complications related to the program. The program induced a significantly increase in functional capacity measured by the six-minute walking test (510.7 + 62 m vs 534.3 + 71 m, p = 0.007) and the chair test (13.2 + 4, 7 vs 16.4 + 7 repetitions, p = 0.02), as well as an increase in the level of physical activity measured by the Yale physical activity questionnaire (37.6 + 20 vs 54.2 + 27; p = 00029). CONCLUSIONS: Multimodal prehabilitation in patients candidates for elective cardiac surgery is feasible and it increases functional capacity preoperatively without being associated with complications. The presumed beneficial impact of this improvement on the incidence of postoperative complications and hospital stay, requires further investigation.

Unilateral pulmonary edema associated factors after minimally invasive mitral valve surgery.

BACKGROUND AND OBJECTIVES: In recent years, minimally invasive cardiac surgery (MICS) has been developed and applied to a greater number of pathologies, especially in mitral valve surgeries, as it obtains results comparable to those of conventional techniques while entailing lower surgical trauma and shorter recovery time. MICS requiring one-lung ventilation has been associated to the appearance of unilateral pulmonary edema (UPE), which is a potentially serious complication. The objective is determining the incidence of UPE after mitral MICS and its development associated factors. MATERIAL AND METHODS: Observational descriptive and single-center study analyzing data from patients undergoing mitral valve MICS (right mini-thoracotomy) consecutively collected between the years 2015 and 2017. RESULTS: A total of 93 patients were included and 26 presented UPE. The most common complications after mitral valve MICS were atrial fibrillation (38.7%), UPE (28%) and transient and/or definitive second- or third-degree auriculoventricular block (19.4%). The UPE group had longer ICU stay (3.3 ± 8.0 vs. 1.84 ± 2.23 days) and longer total hospitalization length-of-stay (15.5 ± 34.7 vs. 10.6 ± 7.5 days). The mortality in the UPE group was 3.9%. A significant association was found between the following collected variables and the development of postoperative UPE: preoperative baseline pulse oximetry, preoperative use of ACE inhibitors, postoperative atrial fibrillation and 24 first-hours cumulative chest tube drainage volume on the first 24 h. CONCLUSIONS: The incidence of UPE is high and its appearance is associated with a longer ICU and total length of stay. More studies are required to understand its pathophysiology and apply measures to help decreasing its appearance.

Factores asociados al edema pulmonar unilateral después de la cirugía mínimamente invasiva de la válvula mitral / Unilateral pulmonary edema associated factors after minimally invasive mitral valve surgery

Antecedentes y objetivo: En los últimos años la cirugía cardíaca mínimamente invasiva (CCMI) se ha desarrollado y aplicado a mayor número de dolencias, especialmente en cirugías sobre la válvula mitral, por presentar resultados comparables a las técnicas convencionales con menor agresividad y tiempo de recuperación. La CCMI que necesita ventilación unipulmonar se ha asociado a la aparición de edema pulmonar unilateral (EPU), que constituye una complicación potencialmente grave. El objetivo es determinar la incidencia de EPU tras CCMI mitral y los factores asociados a su desarrollo. Material y métodos: Estudio observacional descriptivo y unicéntrico. Se analizaron los pacientes tratados con CCMI sobre válvula mitral (minitoracotomía derecha), recogidos de manera consecutiva entre los años 2015 y 2017. Resultados: Se incluyó a un total de 93 pacientes, de los cuales 26 presentaron EPU. Las complicaciones más habituales tras la CCMI mitral fueron: fibrilación auricular (38,7%), EPU (28%) y bloqueo auriculoventricular de segundo o tercer grado transitorio o definitivo (19,4%). El grupo EPU presentó mayor tiempo de estancia en UCI (3,3±8,0 vs. 1,84±2,23 días) y mayor tiempo total de hospitalización (15,5±34,7 vs. 10,6±7,5 días). La mortalidad en el grupo EPU fue del 3,9%. Se encontró asociación significativa entre las siguientes variables recogidas y el desarrollo de EPU postoperatorio: pulsioximetría basal preoperatoria, uso preoperatorio de IECA, fibrilación auricular postoperatoria y volumen de drenajes en las primeras 24h. Conclusiones: La incidencia de EPU es elevada y su aparición se asocia a mayor estancia en UCI y mayor tiempo total de hospitalización. Se requieren más estudios para comprender su fisiopatología y aplicar medidas que ayuden a disminuir su aparición.(AU)

Complications of continuous catheter analgesia for postoperative pain management in a tertiary care hospital. Incidence of technical complications and alternative analgesia methods used. / Complicaciones de la analgesia continua invasiva para el control del dolor agudo postoperatorio en un hospital de tercer nivel. Incidencia de complicaciones técnicas y uso de métodos de analgesia alternativos.

BACKGROUND: Continuous invasive analgesia remains the gold-standard method for managing acute post-operative pain after major surgery. However, this procedure is not exempt from complications that may have detrimental effects on the patient and affect the post-operative recovery process. Data of the complications of continuous catheter analgesic techniques (CCATs) and their impact on pain relief are scarce in the literature. MATERIAL AND METHODS: We conducted a prospective longitudinal study and patients who underwent a surgical procedure and received continuous invasive analgesia after surgery were included. Post-operative analgesic strategy, pain scores (NRS), CCAT's characteristics and technical complications were recorded. Patient satisfaction was determined. Descriptive statistics and Student's t-tests were applied for the comparative analyses. RESULTS: We collected data from 106 patients. Mean duration of the CCAT was 47.52±21.23hours and 52 patients (49.1%) were controlled in conventional hospitalisation units whereas 54 patients (50.9%) were controlled on intensive or high-dependency care units. The overall incidence of technical complications was 9.43%. The most common complications were catheter displacement (2.38%), inflammation at the IV catheter insertion point (2.38%) and excessive dosing of analgesic drugs (2.38%). Mean NRS scores were ≤3 during the permanence of CCATs. Maximum pain intensity was significantly higher in patients who suffered technical complications (mean±standard deviation [x̅ ± SD]: 4.4 ± 2.8 vs. 2.9 ± 1.9; P<0.05). Satisfaction levels with the technique and overall satisfaction with the pain management strategy were negatively impacted by the occurrence of complications. CONCLUSIONS: The incidence of technical complications of CCATs was 9.43% and had a negative impact in pain control and patient's satisfaction.

Importancia de la ecocardiografía transesofágica intraoperatoria en la decisión quirúrgica en cirugía cardiaca / The importance of intraoperative transesophageal echocardiography in the surgical decision in cardiac surgery

Objetivo. Determinar la importancia de la ecocardiografía transesofágica (ECOTE) intraoperatoria en la decisión quirúrgica en pacientes intervenidos de cirugía cardiaca. Pacientes y método. Estudio prospectivo observacional en pacientes de cirugía cardiaca intervenidos desde enero de 2009 hasta mayo de 2012, a los que se monitorizó con ECOTE por el anestesiólogo responsable. Los datos recogidos fueron: 1) tipo de cirugía; 2) diagnóstico ecocardiográfico preoperatorio (ECO basal); 3) diagnóstico ecocardiográfico antes de entrar en circulación extracorpórea (CEC) (ECOTE pre-CEC); 4) si había diferencias entre la ECO basal y la ECOTE pre-CEC (hallazgo nuevo pre-CEC) y si estas diferencias modificaban la cirugía planeada, y 5) diagnóstico ecocardiográfico después de la desconexión de CEC (hallazgo no esperado pos-CEC) y si estos hallazgos ecocardiográficos pos-CEC hacían reinstaurarla. Para el análisis de datos se utilizó el programa de software SPSS(R). Resultados. El total de pacientes estudiados fue de 1.273; la monitorización con ECOTE mostró «hallazgos nuevos pre-CEC» en 98 pacientes (7,7%) y en 43,8% de estos modificó la cirugía programada; de estos hallazgos, los más frecuentes fueron alteraciones de la válvula mitral que no habían sido diagnosticadas, lo que determinó la sustitución o reparación de la misma que no estaba programada. La incidencia de «hallazgos no esperados pos-CEC» fue del 6,2% (79 pacientes), y de estos, en el 46,8% se requirió reinstaurar la CEC y modificar la cirugía realizada. Las reparaciones valvulares fallidas y las prótesis valvulares disfuncionantes fueron las causas principales que motivaron la reentrada en CEC. En los 42 pacientes restantes, con «hallazgos no esperados pos-CEC», no hubo cambios en la conducta quirúrgica, ya que se consideró que el hallazgo ecocardiográfico no era lo suficientemente significativo como para reinstaurar la CEC y revisar o cambiar el procedimiento quirúrgico. Conclusión. En cirugía cardiaca, la monitorización intraoperatoria con ECOTE por el anestesiólogo aporta información importante antes y después de la CEC que modificó el manejo quirúrgico (AU)

Objective. To determine the importance of intraoperative transesophageal echocardiography (IOTEE) in the surgical decision in patients undergoing cardiac surgery. Patients and method. Prospective observational study of patients undergoing cardiac surgery from January 2009 to May 2012, which was monitored with IOTEE by the anesthesiologist in charge. The data collected were: 1) type of surgery; 2) preoperative echocardiographic diagnosis (baseline ECHO); 3) echocardiographic diagnosis before entering cardiopulmonary bypass (CPB) (pre-CPB IOTEE); 4) any differences between the baseline ECHO and the pre-CPB IOTEE (new pre-CPB finding) and whether these differences modified the planned surgery, and 5) echocardiographic diagnosis after disconnection of CPB (unexpected post-CPB finding) and whether these post-CPB echocardiographic findings led to reinstating it. The software program SPSS(R) was used for data analysis. Results. The total number of patients studied was 1,273. Monitoring with IOTEE showed 'new pre-CPB' findings in 98 patients (7.7%), and 43.8% of these led to a change in the scheduled surgery. Of these findings, the most frequent were abnormalities of the mitral valve that had not been diagnosed, and which led to a replacement or repair that had not been scheduled. The incidence of 'unexpected post-CPB findings' was 6.2% (79 patients), and 46.8% of those required reinstating the CPB and modifying the surgery performed. The failed valve repairs and dysfunctional valve prostheses were the main causes that led to re-entry into CPB. In the remaining 42 patients, with 'unexpected post-CPB findings', there were no changes in the surgical procedure as the echocardiographic findings were not considered to be significant enough to re-establish CPB and revise or change the surgical procedure. Conclusion. Intraoperative monitoring with IOTEE by the anesthesiologist during surgery provides important information before and after the CPB that resulted in modifying surgical management (AU)

Manejo perioperatorio de la fibrilación auricular / Perioperative management of atrial fibrillation

La fibrilación auricular es una complicación frecuente en el periodo perioperatorio, y cuando aparece se incrementa el riesgo de morbimortalidad perioperatoria debido a ACV, tromboembolismo, fallo cardiaco, IAM, hemorragia debida a anticoagulación y reingresos hospitalarios. En el presente artículo se recogen las recomendaciones para el manejo de la fibrilación auricular perioperatoria basándose en las últimas Guías de Práctica Clínica de la fibrilación auricular publicadas por la Sociedad Europea de Cardiología y la Sociedad Española de Cardiología, prestando atención tanto a su optimización preoperatoria, como al manejo del episodio agudo perioperatorio. En este sentido se incluyen las últimas recomendaciones para control de la frecuencia cardiaca, control del ritmo y anticoagulación (AU)

Atrial fibrillation is a frequent complication in the perioperative period. When it appears there is an increased risk of perioperative morbidity due to stroke, thromboembolism, cardiac arrest, myocardial infarction, anticoagulation haemorrhage, and hospital readmissions. The current article focuses on the recommendations for the management of perioperative atrial fibrillation based on the latest Clinical Practice Guidelines on atrial fibrillation by the European Society of Cardiology and the Spanish Society of Cardiology. This article pays special attention to the preoperative management, as well as to the acute perioperative episode. For this reason, the latest recommendations for the control of cardiac frequency, antiarrhythmic treatment and anticoagulation are included (AU)

[Preoperative adverse events during stereotactic microelectrode-guided deep brain surgery in Parkinson's disease]. / Incidencias peroperatorias durante la cirugía estereotáctica con utilización de microelectrodos intracerebrales profundos en la enfermedad de Parkinson.

OBJECTIVES: To evaluate the prevalence of adverse events and complications during surgery using deep brain electrodes, mainly in the treatment of Parkinsonism. To describe the adjustment of propofol to meet the needs of neurophysiological monitoring. PATIENTS AND METHODS: A prospective study of patients undergoing stereotactic microelectrode-guided deep brain surgery (stereotactic pallidotomy, implantation of electrodes in the thalamic or subthalamic neurons of the globus pallidus). After placement of a stereotactic frame and completion of a computed tomography scan of the head, the patients were transferred to the operating room. Monitoring included electrocardiography, pulse oximetry, arterial pressure (invasive), endtidal carbon dioxide pressure, and diuresis. Anesthesia was maintained by intermittent infusion of propofol. Variables recorded were age, sex, disease and time elapsed since diagnosis, surgical complications and their treatment, total dose of propofol, duration of surgery, and place of transfer for recovery. RESULTS: One hundred twenty-eight patients (50 women, 78 men) with a mean (+/- SD) age of 59.6 +/- 10.2 years underwent the procedure from 1996 through 2003. The mean time elapsed since diagnosis of the disease was 14 +/- 6.2 years. The propofol dose was 890.6 +/- 571.4 mg and duration of surgery was 8.3 +/- 2.4 hours. Adverse events were observed for 101 patients (78.9%). The most common complications involved hemodynamics: arterial hypertension (59.4%), bradycardia (18.0%), arterial hypotension (7.9%), and tachycardia (6.2%). Other more serious complications were pneumocephalus with clinical repercussions (3 cases), globus pallidus hematoma (2), air embolism (2), epileptic seizure (3), anisocoria (1), and dyspnea and/or airway obstruction (7). CONCLUSIONS: Deep brain stimulation requires surgery of long duration. Because of frequent episodes of arterial hypertension, which increases the risk of brain hemorrhage, and other less common but potentially dangerous complications, careful clinical monitoring is necessary during the procedure. The intermittent use of propofol does not interfere with neurophysiological monitoring.
